The Allen-Bradley 1747-UIC is a universal interface converter, allowing you to connect devices using programming cable to the USB port of your computer and a DH-485 protocol. This interface converter works with different versions of Linux and Windows thus making it suitable for a wide range of users. Also, it has three LED indicators showing if the USB port is powered, operational, and receiving data, and whether the data is actively passing. That makes it easier to notice if there's a problem and saves time.
